Introduction

TBD

Mount Graham red squirrel habitats in 2001 (top) and in 2011 (bottom) after the large wildfires of 2004.

Green is evergreen forest; tan and whitish are shrub/scrub and grassland.



Least Bell’s Vireo habitat in CH in 2001 (top), 2011 (middle), and the change in habitats from 2001-2011.

Reds are classified as development of varying intensity; shades of brown and gray are ‘natural’ habitat.

Species

The percentage of critical habitat that changed from one NLCD class to another ranged from 0.1 to 53.7 per species. The average amount of change was 5.1% (median = 2%).

The proportions of habitat transitions varies by species. For example, the Mt. Graham red squirrel had the largest proportion of its habitat change, primarily because of a [[year]] fire

Whooping crane, which saw 3%, or >11,000 acres, of habitat change within critical habitat:

Habitats

We next asked if there were systematic habitat transitions across species. MORE

To see which habitat was converted to which habitat, we can create a heatmap. Note that the acres are log10-transformed because the area of shrub/scrub is so large relative to other areas:

Appendix

To facilitate species-by-species evaluation of habitat changes, we provide ‘from:to’ heatmaps for each of the 42 species in the dataset:
